INCUBATOR.

To all whom it may concern:

Be it. known that l, ARTHUR E. ALLisoN, a citizen of the United States,and a resident of Coatesville, Chester county, Pennsylvania, haveinvented certain Improvements in incubatore, of which the following is aSpecification.

My invention relates to apparatus employed for the artificial incubationof eggs, and the iuain object of my' invention is to provide a structurethat is entirely automatic in its action, being operated by the -forceexerted by a volume of liquid under suitable head, which liquid may he ahydrocarbon fuel to be subsequently fed to a suitable burner to 4providethe necessary heating oi the structure 'llhese and other features oi' myinvention are more 'fully described hereinaftemreference boing had toVthe accompanying drawings. irrivliieh Figure l, isa side elevation ofan incubatonijuidc in accordance with my. iiiveni A comprises burnerstructure l I drocarbon or other liqiild fuel employed, be centrallydisposed with respect to lion;

My improved incubator comprises a suitable trame or striwtui',M 1supportedby legs 2, andsurh strns'tur may be circular in cross sectionalcontour. A platform '3 is provided for the support of the heating means.4, andthe egg chamber is.' closedv by a lolror cover' The egg chamberproper afixed base or platform 6, carrying the eggs to by an annularwall or casing'i adapted to telescope within the upper portion of thestructure indicated by the-annular wall or easing 7% This movement `ofthe casing 7 takes place at intervals sircd airing of the eggs. Themeans for operating this part of the structure are more l `referred tohereinafter an particularly as to have the extent they may be timed soof airing of greater or less duration as may be necessary or desirable.The lamp burner or other heating device 4, preferably a .designed togasify the hymay I 'the structure, being 'carried by theplatformippiiceiion and august 1a, 191s. y

3, and leading from this burner is the usual chimney 9, surrounded by aheat chamber 10; the latter communicating via'apertures 11 with theupper portion of the incubating chamber. The casing 7 of this chamber israised and lowered aty regular `jiiteriials` as. hereinafter described,and 2during -thei raising or lowering operation, preferablyl the former,the eggs are turn by a special tiiming device, more particularlydescribed hereinafter.

The operation of the structure is entirely automatic, and for thispurpose the following mechanism is employed; 15 representen tankcontaining asuitable liquid, which may be hydrocarbon` fuel, keroseneo1" sim'i lar material employed as the heating means, or Wat-er or otherliquid, which delivers by way of a pipe .16 through a straightway valve17, a three-wayvalve 18, and a short pipe section 16*i supported by `theframe or casing" of the machine; Which chamber 19- contains a piston 20carried by a piston rod 21,`and' these parts 20 and 21 are raised by theforce im.- parted by the-head oit liquid entering the chamber 19 belowthe piston 20. lTo the lower end' of the piston rod .is connected a cord22, attached to and assing partly around asheave carried y a shaft 24.Carried by said shaft is a second sheave 23 to which is attached asecond cord 22* which passes around a sheave 25 mounted on the axis ofthe egg carrier; the opposite e'ndof said latter cord passing overanothersheave 2G supported Yby a bracket 27 securedto the egg support,and has at its lower lend a weight 28. In addition, 'the shaft 24 cuil-I ries a pair of sheaves-29 to which cords 30 are attached which passoverv sheaves' .31 carried by studs 32 supported by the frame of thestructure, thel opposite ends of which cords are connected at 33. totubular arms 34 carried by themovable portion 7 of the egg chamber, and`when the shaft 24' .is turned by means medium of the sheaves 29 willing 7 ofthe 'egg chamberto a' stantially at or near the top of t ecasing. It will be understood, of course, that yother equivalent meansmay be employed to effect casing 7, for instance rack and pinionconnections. Y

(Asshown in Fig. 4, both floats 52 and 55 are in the lower position.)

The rod 56 of the oat 55 is connected at its upper end to one end of alever 61- ivotally mounted at 62, the opposite ,en of which lever isconnected by means of a link 63 to an arm 64 of the valve 17, and
